Abstract
This utility model relates to a kind of outdoor metal armoured voltage transformer, and including base plate and metal shell, metal shell is interior through epoxy resin outer cladding voltage transformer, connecting bottom board bottom metal shell；Side, described metal shell top connects silica gel end through ring flange, and metal shell bottom opposite side is provided with secondary terminal box.Outdoor metal armoured voltage transformer shell is connected with base plate and ground connection, its surface is not charged tangibly when normal work, and it will not produce the phenomenons such as arcing, safety and life-span and all be far above conventional outdoor voltage transformer under the conditions of harsh climate.
Description
Technical field
This utility model relates to voltage transformer field, particularly relates to a kind of outdoor metal armoured voltage transformer.
Background technology
Existing metal armoured voltage transformer is all used in secondary in gas-filling cabinet and uses cable to draw wiring, and conventional
Outdoor products is all directly to use outdoor resin-cast form or the transformer of compound inslation form, its table when normal work
Face is charged, the most tangibly；And the phenomena impair such as arcing service life is easily produced when vile weathers such as sleet dense fogs.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides outdoor metal armoured mutual induction of voltage
Device.
The technical solution adopted in the utility model is: a kind of outdoor metal armoured voltage transformer, including base plate and
Metal shell, through epoxy resin outer cladding voltage transformer, connecting bottom board bottom metal shell in metal shell；Its feature exists
In: side, described metal shell top connects silica gel end through ring flange, and metal shell bottom opposite side is provided with secondary connection
Box.
Further, described ring flange two sides is all arranged on metal shell by stainless steel screw with sealing ring.
Further, described secondary terminal box and metal shell contact surface are with sealing ring, and equipped with two in rosette
Water joint penetrates rosette for secondary line and carries out wiring, and with the waterproof waterproof vent valve of open air use.
Beneficial effect the most of the present utility model: outdoor metal armoured voltage transformer shell with
Base plate connects and ground connection, and its surface is not charged tangibly when normal work, and under the conditions of harsh climate its
Will not produce the phenomenons such as arcing, safety and life-span is all far above conventional outdoor voltage transformer.Silica gel end and secondary connect
Line box is equipped with sealing ring with being connected between metal shell, good seal performance, coordinates water joint and waterproof vent valve, effectively simultaneously
Guarantee that secondary terminal box wiring is waterproof.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
In figure: base plate 1, metal shell 2, ring flange 3, silica gel cable connector 4, secondary terminal box 5, water joint 6, waterproof
Vent valve 7.
Detailed description of the invention
It is described further below in conjunction with drawings and Examples.
Shown in Fig. 1: a kind of outdoor metal armoured voltage transformer includes base plate 1 and metal shell 2, metal shell 2
Interior through epoxy resin outer cladding voltage transformer, connecting bottom board bottom metal shell 2；Side, metal shell 2 top is through ring flange 3
Connecting silica gel end 4, metal shell 2 bottom opposite side is provided with secondary terminal box 5.Ring flange 3 two sides all leads to sealing ring
Cross stainless steel screw to be arranged on metal shell 2.Secondary terminal box 5 and metal shell 2 contact surface are with sealing ring, and rosette
On penetrate rosette equipped with two water joints 6 for secondary line and carry out wiring, and with waterproof waterproof of open air use
Air valve 7.
It is connected mutually through cable connector with lead-in wire spring through leading-out terminal of the voltage transformer of epoxy resin outer cladding
Terminal of sensor, the secondary outgoing line end connecting secondary rosette of voltage transformer.
